cjdnsadmin.py

Using cjdnsadmin.py is trivially simple, you can connect to a router and issue it commands in 3 steps:

from cjdnsadmin.cjdnsadmin import connect;

Make sure cjdnsadmin/cjdnsadmin.py and cjdnsadmin/bencode.py are in your path, the easiest thing to do is put cjdnsadmin/ in the same directory as your script.

connect()

This takes 3 parameters, the ip address of the listening router, it's port number, and the password to connect to it. These can be found in your cjdroute.conf here:

"admin":
{
    // Port to bind the admin RPC server to.
    "bind": "127.0.0.1:11234",

    // Password for admin RPC server.
    "password": "4s8mshm4hbb2lbdwz4bxfdn9w7"
},

To connect to this node, you would use:

cjdns = connect('127.0.0.1', 11234, '4s8mshm4hbb2lbdwz4bxfdn9w7');

The password will be checked when you connect and if it's incorrect you will get an exception.

Or just use

from cjdnsadmin.cjdnsadmin import connectWithAdminInfo;
cjdns = connectWithAdminInfo();

It get data from ~/.cjdnsadmin

Use it!

The cjdns object returned from connect() and connectWithAdminInfo() contains functions corrisponding to each of the RPC calls in the router. There is a field called cjdns.functions which contains a list of the functions and their parameters.

For convenience, you can directly start ./cjdnsa
